original applicationfiled December to, tail, serial No. ace-eta. Dividedand this application filed march To all whom it may concern:

Be it known. that l, 'loNJns Answer CARL Born, a citizen of the UnitedStates, and a resident of Malden, in the county of Middlesex and Stateof Massachusetts, have invented certain new and useful Improve ments inMechanical Movements, of which the following is a specification, takenin connection with the accompanying drawing, which forms a part of thesame, this application being a division of my copending applicationSerial No. 668,632, for improvement in mechanical movements andelectriclight sockets.

My invention relates to mechanical movements adapted for universalapplication. 1F urther to electric light sockets and to certain detailsof construction of both the mechanical movement and the electric lightsocket, which will be more fully hereinafter described in thespecification and pointed out in the claims.

I have shown my mechanical movement as a switch mechanism in an electriclight socket, to which it is particularly adapted owing to itssimplicity, the few parts, and the small space occupied by them. When soused, it makes a quick make and a quick break of the electric current,without arcing, upon the operation of the driving member in eitherdirection.

v Among other advantages my mechanical movement permits the socket to beformed smaller and stronger for the opening in which the mechanicalmovement is mounted need not be so large as for other switch mechanism.ln illustrating my invention l have, therefore, by way of example, shownit as a switch mechanism in an electric light socket, but it is to beunderstood, of course, that the mechanical movement is not to be limitedto this use.

lln the accompanying drawing showing illustrative embodiments oil myinvention and in which the same reference numerals refer to similarparts in the several figures, Figure l is a transverse horizontalsection substantially on the line l-l oi Fig. 2: Fig. 2 is a sideelevation of my improved electric light socket, partly broken away; Fig.3 is a side elevation of my electric light socket, looking in thedirection of the arrow 3; of Fig... 2; Fig. t is a side elevation of aPreferably l Serial No. aerate.

modified form of intermediate or hill and valley member; Fig. 5' is aplan view of the intermediate member illustrated in Fig. at.

In the illustrative embodiments of my invention shown in the drawing, 1is an electric light socket including an insulating member 2 formed of aplurality of parts. form the insulating mem' her 2' of two complementaryparts 3 and l, each of them being provided with recesses 5 and 6 to forman interior chamber '2 within which my mechanical movement is mounted.The recess 6 in the member 3 is provided with two openings 8, 8 toreceive the driving members or push buttons 9 and 10., These buttons areprovided with shoulders ll, 11 which coeperate with the shoulders l2, 12in the insulating member 3 to limit the outward movement of therespective driving members or push buttons.

My driven member is preferably a resilient member such as the spring 13which will be caused to reciprocate with a quick snap within the chamber7 formed by the two openings 5, 6* in the members 3 and 4:. While ll mayuse any suitable form of intermediate movable, or bill and valleymember, ll preterably use such a member formed out oil? insulatingmaterial such as M which is pivoted on the pin 15 and is" connected bythe pins 16, 1'6, at its respective ends, to the driving members whichas illustrated are push buttons 9 and 10. The pin 15 is prob erablyjournaled in the grooves 37, 37 on the insulating member 3.

By pushing in the driving member or push button 9, the intermediatemovable hill and valley member M will be caused to rock upon its pin 15and will store up the power in the driven resilient member l3 until suchtime as the kicker or accelerator 17 crowds orpushes theend 18 of theresilient driven member 13 out of the valley 1% and over the ledge 20when the entire resilient member 13 will snap over with a quick snap andwhen employed as a switch mechanism make a connection between the screwshell contact 21, Fig. 2, carried by the screw shell 22 and the contact23 of the binding ost 2t carrying the binding screw 25'. When themechanical movement is used as a switch mechanism and it is desired todisconnect the consuming device, it is merely necessary to llltl lllfldepress the driving member or push button 10 which will have then beenelevated. Alternate pressure upon the driving members or push buttons,whichever push button is for the moment extended, will cause theresilient driven member 13 to alternately snap into and out of 'contactwith the contacts 21 and 23.

The binding post 26 is provided with an arm 27 which is the centercontact for the consuming device. This binding post 26 is provided witha binding screw 28 and is held to the insulating member 3 by means ofthe locking screw 29. The binding post 24 is secured to the insulatingmember 4 by the locking screw 30 which is passed through the insulatingmembers in the opposite direction from the locking screw 29. In thismanner the insulating members are secured together at the same time thatthese screws secure the binding post to the insulating members. Thissame operation will also secure the screw shell 22 to the insulatingmembers 8 and 4 by holding the dovetail surfaces 31 on the insulatingmembers in contact with the dovetail 32 011 the screw shell 22.

The intermediate member 14 I preferably form in any suitable manner outof some insulating material as porcelain so as to insulate the drivenmember 13 from the push buttons '9 and 10 permitting them to be formedout of metal or conducting material Without being provided with aninsulating operating surface. I may, however, in some cases make thisintermediate member out of metal. In Fig. 4 I have shown an intermediatemember 33 made from a stamping and provided with the valleys 34:, 34:each valley having a ledge .35. Associated with each valley is alsopreferably an accelerator or kicker 36 to crowd orkick the operating endof the resilient driven member 13 out of the valley, upon theintermediate movable member reaching a certain predetermined position,thereby permitting the operating end of the spring to fly from onevalley to the other and at the same time cause the en tire resilientmember to move laterally with a quick and positive snap. I alsopreferably provide the intermediate member with the trunnions 38, 38 tobe received inthe grooves 87, 3'? in the insulating member it whichforms a bearing for the intermediate member.

My mechanical movement converts a slow or fast pressure on the raiseddrivingmemher into a quick and positive reciprocating movement of theresilient driven member 13. When used as a switch mechanism, as shown,it serves to make a quick make and a quiclr. break of the electriccurrent, without arcing, upon operating the push buttons.

My push buttons, it will be noted, are located on the same side of thesocket and jacent to each other forming a strong me chanical structureand one which can be readily operated with the minimum inconvenience.This arrangement of the push buttons is also quite pleasing to the eye.

My improved socket is adapted to be used without the usual socket shelland cap, though I preferably surround my socket with such a shell andcap. As these, however, are no part of my present invention, I haveomittedfthem from the drawing.

It would be possible in some cases to use only one push button ordriving member which would be pushed in in the ordinary manner. It wouldbe moved in the other direction by pulling on it in any suitable manneras by grasping it by the thumb and finger. My invention, therefore,includes either one or more push buttons for actuating the intermediatemember. Preferably, I use two such push buttons, as shown.
